funktel FC4 LF

Professional DECT handset with automatic alarm triggering

The funktel FC4 LF offers a GAP-compatible, high-quality DECT handset for professional applications. All funktel FC4 models are also fully compatible with the I1/3/5 and I55 cellular integral DECT systems. Thanks to the colour display, illuminated keypad, lithium-ion battery, incoming and outgoing call logs as well as messaging lists and a sturdy design these handsets are certainly a welcome addition to your communication system.
Comfortable handling features such as hands-free operation, MIDI ringtones, vibration alarm signalling, easy operation using symbol-based user interface and memory-storage of the settings on a replaceable memory card (SIM card) are all part of the offering.

In addition, the FC4 LF also includes an integrated position sensor that automaically triggers as alarm to call a specified number as soon as the device is moved more than 55° from a vertical position. A programmable pre-alarm (tone/vibration) prevents premature alarm signals, but if not reset a call is automatically made to a freely programmable thelephone number with hands-free operation - a very useful aid in an emergency.
